' 3 claims. l (ci. 139-420) z Efforts havebeen made in xthe past; to make use of vsisal as a c onstituent in rug weaving, but difficulties have been encountered by reason of the stiff wiry character of the filaments, `which resist packing or copression and make itqdifficult to beatup the sisal-strands in the loom, so that, unless the vfiber strands are., firmly andpermanently anchored in place, the rug will be sleazy or loose-texturedand will not maintain its shape.

Sisal possesses certain very desirable qualities, however, principally by reason of its bright lustrous appearance and its ability to take permanent dyes, so that the use of small quantities of sisal has heretofore been attempted for the purpose of brightening the appearance of the rug, and maintaining an apparent newness or freshness even after the dull and less permanently dyed materials have faded. Such use of sisal in the past, however, has been limited mainly to narrow warp stripes which were closely compacted by the proximity of the more compressible materials so that it was possible to hold the sisal warp stripes in position. I have found, however, that highly satisfactory results can be secured by the use of a sisal woo-f or ller in conjunction with a fiber warp, by which is means a warp in which the strands are composed of twistedpaper known in the art as ber.

The fiber, however, is off a mitch duller color tone and colored with relatively impermanent dyes as compared with the lustrous tones of the sisal which serves to brighten the rug and give it a permanent luster, so that the fading of the fiber will not kunduly impair the appearance of the rug, which will thus maintain its freshness for a long period of time.

Further objects and details will appear from a description of the invention in conjunction with the accompanying drawing, whe-rein- Figure 1 is a section of a rug displaying the characteristics of the present invention; and

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

The rug consists of Woof strands A of permanently ycolored sisal of relatively heavy bulk as compared with the warp strands B of fiber twine of relatively duller color tones and dyed with relatively impermanent dyes as compared with the dying of the sisal.

The contiguous woof strands are united by the bends of loops C at the edges of the rug, so that the Woof strands are practically continuous throughout substantial areas of the rug, and the outwardly presented loops serve to aord the finished side edges of the rug. The individual warp strands are of much smaller bulk thanthe woof strands and are arranged in pairs, each pair being looped over two woofstrands and under the next two, and the pairs of warp strands are twill woven so as `to give a diagonally ribbed effect throughout the rug.

Y, As sho-wn, the entire woof of the rug is composed of the bulky sisal strands and the entire Warp of theless bulky fiber strands, with the exception of one or more warp stripes D of sisal which as shown are of equal bulk with the sisal strands in the woor.` The use of occasional sisal warp strands intersecting the sisal woof strands is permissible in limited degree where the number of adjacent warp strands is -very limited, as for instance two or possibly three warp strands, so that the areas of intersection of the sisal strands (warp and woof) are so reduced as to hold the sisal permanently anchored against displacement by the compacting influence of the adjacent fiber, which latter is a readily `cornpactible substance which serves admirably for the purpose of holding the sisal strands in place.

As before stated, the fiber Warp is dyed with relatively impermanent dyes, which affords a somewhat dull or non-lustrous color tone in marked contrast to the lustrous silvery appearance of the natural sisal, or the lustrous color tones imparted by dyeing with permanent dyes, so that, by employing a ller of relatively bulky sisal strands, large areas of the sisal are exposed in the completed rug which thus displays the lustrous coloration of the sisal and compensates against the duller tones of the ber, or the tendency of the latter to fade after a period of use.

By employing the sisal exclusively in the woof of the rug, with the possible exception of narrow warp stripes, the sisal strands will lie in adjacent relation to one another throughout all, or practically all, of the entire area, so that there will be no areas of intersection, except .possibly the limited areas where narrow sisal warp stripes are used tor pattern effect or otherwise, with the result that the strands composing the sisal Woof will be firmly and permanently lanchored by the compactible fiber warp, so that a closely textured and firmly interwoven rug will be provided which secures the advantages of a large display of sisal without permitting the sisal strands to escape the close confinement necessary in order to prevent warping or stretching of the rug. f

Furthermore, the sisal affords a strong, re-

silient or springy Woof .by reason of :the wiry character -of the sisal filaments composing the Woof strands, so that the rug will not tend to mat down in use, but will maintain |a springy resilient texture for an indefinite period of time, and at the same time the compressible resilient character of the bulky sisal Woof affords a backing for the exposed liber warp, which guards the latter against abrasive action, which is highly desirable, since the latter, unless protected by a resilient backing, would be subject to deteriora-` tion through abrasive action.

The combination of sisal and ber here described has proved to be highly satisfactory in commercial use, both by reason of the striking appearance of the rug and .by reason of its durable and resistant qualities, as well as Iby i-ts freedom from warping due to displacementof the sisal strands.

I claim:

1. A rug composed. throughout substantially its entire area of `closely lying parallel wolof strands of lustrous sisal and warp strands of dull toned ber, the ber warp strands being interwoven with the sisal Woof strands and closely compacte-d to anchor the wooi strands against displacement, the sisal strands being dyed at least in part With relatively permanent dyes and displaying a lustrous coloration, and the 2. A rug composed `throughout substantially y its entire area of closely lying parallel Woof strands of relatively lbulky sisal and warp strands of relatively less bulky ber, the ber Warp strands being interwoven with the sisal woof strands `and closely compacted to anchor the Woof strands against displacement, the sisal strands being dyed at least in part with relatively permanent dyes and displaying a lustrous coloration, and the ber strands .being dyed in relatively impenmanent dyes and displaying a duller coloration.

3. A rug consisting throughout substantially its entire area of bulky Woof strands of permanently colored lustrous sisal lying in close parall-el relation and connected by looping at the side edges of the rug, the Woof strands being permanently anchored in place by warp strands interwoven with` the woof strandsand closely compacted to permanently anchor the `sisal-Woof strands against displacement, the individual warp strands being of lesser bulk thanr the sisal woof strands and dyed in relatively impermanent dyes, and presen-ting la relatively dull coloration` as contrasted with the lustrous coloration of the sisal.
